Both dramas are set in a high school. The roof of the school plays a fundamental role. So many mysteries to understand.

Both dramas talk about bullying, and main story line is about a transfer student looking for the truth behind a student's "suicide". Both main characters are not close to the person who died, but it feels like they have something to do with it on the day of the death. There are strong characters who fight the bullies. Both dramas also have characters who lost memories about the event before the student's death.

The overall vibes is very similar, the main character narrated throughout the drama. Both drama has a story where teenager dealing with unfortunate events and involved in crimes then regreting what they've done. Both drama also highlights on bullying that can't be seperated when it comes to korean high-school drama.

Both based on a webtoon.
Both about school bullying.
Both short dramas.
In both dramas, the fighter(s) agree to protect a weaker character.

This two may have a different genre, but if you're a fan of poetry. I think you'll like this. The way how the ML describes a certain happening in the story is like reading a poem.

Both feature bullying. One of the characters ends up being the body guard for another student who is being bullied. Although love isn’t too prevalent, the two boys end up being really the only ones who understand each other.

both are about bromance between high school boys who rely each other, and involve school bullying, street fight and especially Shin Seung Ho, a versatile actor who seems tough and good at fighting.

Both set in high school, these dramas focus on characters which are a bit different and have unique interests. With beautiful touching scenes and a kind of poetic approach, we observe slowly budding friendships embedded in mysteries (although How To Buy A Friend is a tad bit more dramatic whereas Muchuu-sa, Kimi Ni is more carefree).
